A guide to the revised Western Australian Curriculum for Mathematics
Primary Mathematics P-6
This guide contains a clear, concise overview of the key changes to the Western Australian Curriculum for Mathematics (2025) and is designed to save you time and help you plan and implement the new curriculum with confidence.
Why is the Western Australian Curriculum changing?
The revised Western Australian Curriculum for Mathematics has been adapted from the existing curriculum (based on the Australian Curriculum V8.1 -2018), the NESA Syllabus for NSW (2023) and the Australian Curriculum V9.0 (2023).
The new curriculum recognises that each student is developing and achieving in different ways, at different stages and at different rates. The content has been developed to support teachers in planning for teaching, learning and assessment and has been reorganised to show developmental progression across Years P to 6. Familiarisation takes place in 2025 with implementation in 2026.
Western Australian Curriculum
The table below outlines the subject organisation for the P to 6 Mathematics curriculum.

Understanding equalities and inequalities
Two-dimensional space and structures
Patterns and relationships
Calculating with number
MEASUREMENT AND GEOMETRY
Three-dimensional space and structures
Probability
Non-spatial measurement
PROBABILITY AND STATISTICS
Financial mathematics
Modelling with number
Modelling with measurement and geometry (Years 3–6 only)
Statistics
How is the curriculum and content changing?
The new curriculum has been reorganised into renamed sub-strands to support a developmental sequence across Years P to 6. Understanding, Fluency, Problemsolving and Reasoning are embedded in the content descriptions. Information about phases of schooling and achievement standards is also aligned with the revised content descriptions. Key changes include:
• Sub-strands have been re-named and content has been re-organised accordingly
» Number and place value content sits under Understanding number and Understanding equalities and inequalities
» Fractions and decimals content sits under Understanding number
» Calculating with number is a new sub-strand incorporating existing content from Number and place value and Fractions and decimals
» Patterns and algebra beomes Patterns and relationships
» Money and financial mathematics becomes Financial mathematics
» Modelling with number is a new sub-strand
» Two-dimensional space and structures includes 2D shapes, transformation, location, length, area and angles
» Three-dimensional space and structures includes 3D objects, capacity and volume
» Non-spatial measurement includes mass and time
» Modelling with measurement and geometry is a new sub-strand (Years 3–6)
» Chance and Data presentation and interpretation become Probability and Statistics
• Content descriptions include the proficiencies of Understanding, Fluency, Problem-solving and Reasoning
• There is some new content
» Financial literacy is included from Years P to 6
» Probability is included in Year P
» Line graphs are included in Years 5 and 6
• Some content has been reorganised
» Number and place value, Year 1 to Year 5
» Addition and subtraction, Year 2 to Year 6
» Multiplication, Year 1 to Year 4
» Estimation, Year 3 to Year 6
» Fractions, Years 4 and 5
» Percentages, Years 5 and 6
» Patterns, Year P to Year 6
» Australian coins and notes, Years 1 and 2
» Three-dimensional objects, Year P to Year 5
» Transformations, Year 2 to Year 6
» Perimeter, Years 4 and 5
» Area, Year 2 to Year 4
» Volume, Year 2 to Year 6
» Grid maps, Years 3 and 4
» Cartesian plane, Year 6
» Time, Year 1 to Year 3
» Data displays, Year 2 to Year 6
• Information about phases of schooling describes relevant curriculum experiences and aligns with the content descriptions
• Achievement standards align with the content descriptions, with reference to the proficiencies and modelling real-world contexts, and work towards ‘By the end of the year’ rather than ‘At standard’.

Oxford Maths for Western Australian Schools
Our differentiated series, just like the Western Australian curriculum, recognises that each student is developing and achieving in different ways, at different stages and at different rates
Designed by experienced classroom teachers, Oxford Maths for WA:
• helps students make connections with mathematics in the real world and encourages higher-order thinking and reasoning
• includes a wealth of hands-on activities, small-group and whole-group tasks, practice exercises, and open-ended problem-solving opportunities
• ensures every student can access the curriculum at their own point of need.
